Question

Two large metal plates are placed parallel to each other. The inner surfaces of plates are charged by $plus sigma$ and $negative sigma blank left parenthesis C o u l o m b divided by m to the power of 2 end exponent right parenthesis$ . The outer surfaces are neutral. The electric field is …… in the region between the plates and outside the plates

$\frac{2 σ}{\in_{0}}, \frac{σ}{\in_{0}}$
$\frac{σ}{\in_{0}}, z e r o$
$\frac{2 σ}{\in_{0}}, z e r o$
$z e r o, \frac{2 σ}{\in_{0}}$

The correct answer is: $fraction numerator sigma over denominator element of subscript 0 end subscript end fraction comma z e r o$

Between plate $E equals fraction numerator sigma over denominator 2 epsilon subscript 0 end subscript end fraction minus open parentheses fraction numerator negative sigma over denominator 2 epsilon subscript 0 end subscript end fraction close parentheses equals fraction numerator sigma over denominator epsilon subscript 0 end subscript end fraction comma$
Outside plate $sigma equals 0 blank therefore E to the power of ´ end exponent equals 0$
